Add up to 75% more horsepower to your Small Block Chevy at a low cost with the entry level supercharger kit, featuring the Vortech PowerHat™ with diffusion technology.

This is an entry-level "universal"supercharger kit designed for vehicles equipped with carbureted small block Chevrolet engines. Integrates with many existing OEM drive configurations.

This kit requires the installer to supply a high volume fuel pump and properly jetted Holley 4150-type carburetor unit (with mechanical secondaries). Minor (bottom-side) hood support modifications may be required depending upon the vehicle and type of intake manifold installed on the engine.

Most OEM Saginaw type power steering pumps can be attached to the Vortech mounting bracket using the supplied hardware in the kit.

This system was designed to fit on engines equipped with a “long” water pump and OEM V-belt drives or serpentine accessory drives (OEM TPI / TBI applications, 1990-1995 and GM Performance Parts accessory drive system #’s 12497697, 12497698 and 12497869). For correct belt alignment, the proper accessory drive crank pulley and accessory bracketry must be used. These components are not supplied in this kit. Earlier models equipped with short water pumps will require a long water pump to be installed.

The supplied supercharger discharge tube is intended to fit a wide range of manifold heights; however, applications equipped with “high-rise” intake manifolds may require minor adjustment/trimming for optimum fit.

This kit can be used on engines with and without power steering. For engines equipped with power steering and V-belt accessory drives, a Saginaw style pump will be required as well as an optional Vortech power steering pulley assembly. This assembly includes all required hardware, tensioner assembly and anodized billet aluminum pulley. Depending on the vehicle, power steering lines may require fabrication. Optional Vortech power steering pulley and hardware assembly: 4GP110-051.

A compressor bypass valve is suggested for all applications exceeding 5 psig boost. Below is a selection of components available from Vortech (contact Vortech technical department to determine the proper valve selection for the specific application)
